Fastman 84mm truebore throttle body wanted for 18 challenger 6.4

Omgitsmack has good gains on his 6.1 just going with a hellcat tb and adapter plate. Granted his manifold is opened to accept it. Personally I wouldn’t go less than an 88 true bore. If your running an srv manifold, you can open that up a little bit yourself to accept an 88. I wouldn’t expect much gain from an 84. Probably not much from an 88 alone either , but it will compliment future modifications better than an 84.
